Piano Theory & Ear Training
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
41 lessons, every chord and scale in all 12 keys, and 129 ear-training and sight-reading exercises. No ads, no account, works fully offline.
Quiet Keys is a complete piano theory companion — built for anyone who wants to actually understand the music they're playing, not just memorize finger patterns.
WHAT YOU'LL LEARN
• 41 structured lessons, from your very first scale to advanced jazz harmony (ii–V–I progressions, extended chords, modal theory) — organized Beginner through Advanced so you always know what to learn next.
• Every chord in every key — all 12 keys × 13 chord qualities (major, minor, 7ths, extended 9/11/13, half-diminished, and more), each with real audio, inversions, and common progressions.
• Every scale in every key — all 12 keys × 19 scale types, including major and minor variants, all seven modes, pentatonic and blues scales, and exotic scales like harmonic major and Hungarian minor.
• 82 ear-training exercises across five skill types: interval recognition, chord quality, chord inversions, scale recognition, and rhythm — with a real Beginner on-ramp for every single type.
• 47 sight-reading exercises on a real grand staff, treble and bass clef, from single notes to full chords, so you build the skill of reading music at a glance.
WHY QUIET KEYS
• Private by design — no ads, no account required, no tracking of any kind.
• Works completely offline — practice anywhere, no internet needed.
• A Home Screen widget keeps your streak and today's lesson one glance away.
